LUBRICATlNe MECHANISM.

SPECIFICATION forming part of Letters Patent No. 282,837, dated August 7, 1883.

Application tiled .Tune 30, 1883. (No model.) l

To LIZ whom, it may con/cern:

Be it known that I, VARREN M. BRINKER- HOFF, a citizen of the United States, residing at Auburn, in the county of Cayuga and State of New York, have invented new and useful Improvements in Lubricating Mechanism for Hangers, Journal-Bearings, te., of which the following is a specification.

My invention relates to lubricating mechanism for hangers, journals, axles, and other.

bearings, the purpose being to provide the shaft withv a conductor through which .the lubricant is fed to the bearingsurfaee, said conductor being surrounded by a casing havinga chamber or oil-reservoir between the end of the conductor and the top or lid of the casing.

My invention consists in the combination of a shell or casing, a conductor inelosed therein, and a chamber or oil-reservoir between the end of the conductor and the lid of the casing, with means arranged within the casing for constantly maintaining said conductor in contact with the shaft as it is reduced by friction thereon, said conductor being homogeneous throughout, or having a material placed, if desired, within its body, said material being more porous than the latter to facilitate the passage of the lubricant.

Referring to the drawings forming part of this application, Figure 1 is a vertical longitudinal section of a shaft-bearing with lubri cators attached. Fig. 2 is an elevation of the upper side of said bearing. Fig. 3 is a transverse section of Fig. l in the plane 3 3. Fig.4

3 is a detail perspective of the conductingblock shown in Fig. 3. Fig. l4. is a transverse section of Fig. l in the plane et at. Fig. 4 is a detail perspective of a modified form ofthe conducting-block. Fig. 5 is a vertical longitudinal section of a shaft-bearing with lubricators attached. Fig. 6 is an elevation of the top of said shaft-hanger. Fig. 7 is a crosssection in the plane 7 7 of Fig. 5. Fig. 7u is a detail perspective of the conductor shown in Fig. 7. Fig. Sis a cross-section in lthe plane 8 8 of Fig. 5. Fig. 8 is a detail perspective of the conducting-block shown in Fig. 8.

A in said drawings represents the shafthanger or journal-box, which may be of the usual construction. In any suitable part of the box or hanger-bearing is formed an opening, which may be either rectangular or cy-l of said casing, or, if any space intervenes, isy

provided with a suitable packing, by which the escape of the lubricant is prevented. This r conductor may be made of anymaterial whatever-such, for example, as wood, iron, or composition of metal-the sole requirement being that it shall possess sufficient porosity,`

either throughout or in a portion of its body, to permit the passage of the lubricant by capillary action or by permeation, whereby the conductor itself may become a saturated block to furnish the required lubrication.

The casing B is provided with a cover or lid, b, which, in the cylindrical form of casing shown in Figs. 2, 3, 6, and 7 may be threaded upon the open end of the casing, and in the rectangular forni is hinged to one side and fastened by a spring-latch, b', or in any other suitable manner. -Between this lid and the upper end of the conductor Gis placed asuitable spring, D, by which the conductor is held in constant contact with the shaft or journal. Instead of the spring resting against the lid of the casing, it may lie against a cross-bar or other suitable support interposed betweenthe lid or top of .the casing and the end of the conductor, as shown in Fig. 4. of the drawings. Between the upper end of the inelosed conductor C and the lid of the casing B may be formed a chamber, within which the spring D is placed, and this chamber may be utilized as a reservoir for the lubricating material; or said chamber may be formed by recessing the upper end of said conductor, said recess affording space for the lubricant and at the same time a seat for the spring D; or, again, the body ofthe conductor itself may be used as a reservoir for the lubricating fluid or material. V I may place within the body of the conductor an auxiliary conducting substance of any suitable iibrous or porous material, `the ar-A rangement of the parts being substantiallyv shown at E in Figs. l, 2, 3, 5, and 7.

Instead of the form of springl shown at D,

lindrical, by which a portion of the shaft or IOO I may employ any other device by which the conductor C may be drawn or. forced downward or against the shaft; or I may dispense with such 'devices altogether and rely upon gravity to accomplish said result.

It will be seen that by supporting the conductor C within the casing B and the opening in the journal-box, which forms a continuation of said casing, the end of said conductor, which is of light and porous material, is prevented from undue injury or from crumbling away by the friction ofthe shaft, thus providing a more durable and efficient lubricating device than where a block of tallow within -a tubeis maintained in contact with a journal, as in such the heat developed by the revolution of the journal will rapidly melt the tallow, and hence furnish a greater supply of lubricant than is requisite, besides necessitating frequent renewal.

Having thus described my invention, what I claim is l. The combination of ashell or casing, a

' conductor inclosed therein, a chamber or oilreservoir between the end of the conductor and the lid of the casing, with means arranged within the casing for constantly maintaining said conductor in contact with the shaft as it is reduced by friction thereon, substantially as described.

2. The combination with a shell or casing, a

conductor inclosed therein, a porous material.
